After making a giant sixty-factor thing with Cuisenaire rods on Monday, Gabrielle, Marie and Rose were determined to make their own record of what they'd created. We had to stick some squared paper sheets together to make it big enough. They've added a few lines of rods of lengths we don't actually have, giving them new colours!
Can you see, there are still some factors of sixty missing? Do you know what they are?
How did there come to be sixty seconds in a minute, and sixty minutes in an hour? Apparently, it goes back a long way. Have a look at this video:
